Abstract: Abstract:          This invention relates to a speech recognition method, and more particularly to a continuous speech recognition method for recognizing phonemes in continuous speech.  In a matching region in which time-series analytical points of a continuous input speech pattern and a standard pattern exist, a two-dimensional mask is moved on the matching region and is set so as to include a plurality of analytical points of each of the input speech pattern and the standard pattern.  On the basis of analytical results at the analytical points within the mask, the degree of similarity between the input speech pattern and the standard pattern is calculated in a mask unit.  The input speech pattern is thus successively recognized in time series.

Abstract: ABSTRACT    An electronic game device has a main body and a central removable cartridge.   The main body contains circuitry for simulating football, basketball, soccer, and hockey, and the removable cartridge has overlays that register with LEDs on the main body and contain markings peculiar to the game to be simulated.   The cartridge also includes a printed-circuit board that is electrically connected to the circuitry  to indicate which game is to be simulated.    In the basketball, soccer, and hockey versions of the game, two player symbols on each side are provided as well as a game-object symbol, and the game-object symbol can  be displayed in a mode in which it remains stationary during a continuing play indendently of the movement of any other play symbol.  In one version of the game, the game-object symbol, upon encountering the playing-field boundary during pass simulations, is diverted to travel along the boundary.   In another version, scoring can be accomplished both by shooting the game-object symbol into a goal position and by maneuvering it to the goal position under the control of a player symbol.

Abstract: STABLE HIGH COPY NUMBER PLASMIDS                          ABSTRACT         DNA plasmids are described which are selected mutants in which an altered repressor gene leads to high copy number replication.  elements in the plasmids are modified by placing a suitable transcriptional "stop" signal after an inserted heterogenous gene so that readthrough expression of heterologous DNA inserted in the plasmid will not continue into the replication primer strand.  Deletions resulting from interference with replication primer strand transcription are thereby avoided.

Abstract: Abstract Programmable Bipolar Structures A switchable bipolar structure, suitable for use in a programmable read only memory, is provided which includes a rectifying contact disposed on a N type semiconductor substrate with a P type diffusion region formed in the substrate spaced within a minority carrier diffusion length from the rectifying contact  A conductive filament is selectively formed between the rectifying contact and the P type diffusion region by applying d reverse bias voltage between the rectifying contact and the N type substrate having a magnitude sufficiently large so as to form a liquid alloy having a front moving in the direction of current flow.  By maintaining the P type diffusion region at a positive voltage with respect to the voltage on the rectifying contact, the liquid alloy front moves from the rectifying contact to the P type diffusion region forming a conductive filament or segment therebetween.  If the rectifying contact is aluminum and the semiconductor substrate is made of silicon, the filament becomes a silicide made of aluminum and silicon.  By arranging the rectifying contact within a minority carrier diffusion length of, e.g., the base of a NPN transistor, a dense programmable read only memory system may be formed which is programmed by merely applying appropriate pulses of relatively low magnitude to the access lines of the memory system after the system has been fabricated.  Alternatively, a dense Schottky barrier diode read only memory system may be provided by arranging a first rectifying contact within a minority carrier diffusion length of a P type diffusion region which is connected to a second rectifying contact of a Schottky barrier diode to selectively provide parallel current paths through the two rectifying contacts.  In either embodiment, the presence or absence of the filament corresponds to the storing of a o or 1 binary digit or information in the memory systems.

Abstract: MULTIPOLE PINCH METHOD AND APPARATUS FOR PRODUCING     AVERAGE MAGNETIC WELL IN PLASMA CONFINEMENT                 ABSTRACT A multipole plasma pinch method and appara-tus produces hot magnetically confined z-pinch plasma with a plurality of z-pinch current channels arranged so as to generate a multipolar magnetic field and at least one hyperbolic magnetic axis within the plasma space roughly enclosed by the channels, forming there-by a region of average magnetic well in a region of nested closed plasma magnetic surfaces surrounding the plasma current channels, when the magnetic field component in the direction of the hyperbolic axis is also made to be substantially zero in the vicinity of the hyperbolic axis.  The multipole pinch inven-tion may be operated so that q and field reversal take place within the plasma, and the plasma so pro-duced closely approximates known theoretical stability conditions.  The well-producing hyperbolic  axis of the present invention is produced effectively by replacing the solid conducting rings of prior art multipole plasma confinement devices by z-pinch-like toroidal current channel loops of plasma.  The plasma is formed inside a vacuum chamber and an electrically conducting shaping shell assembly, whose noncircular poloidal cross section imparts the desired shape to the plasma.  The shape of the plasma may be maintained and/or adjusted by means of electrical currents driven through appropriately distributed external conductors.

Abstract: ABSTRACT OF THE DISCLOSURE      Very high level of insulation resistance and of in-sulation resistance stability of insulating compositions having polyolefin bases and having polar organic additives are achieved in this invention.  The polar organic additives can be orqanic halogenated flame retardants, such as decabromodiphenyl oxide.  The surprising increase in insulation resistance and in insulation resistance stability is achieved by addition of certain antioxidants in com-bination and, particularly, the addition of a zinc salt of mercaptoimidazole and a sterically hindred ditertiary butyl phenol.  The composition may be crosslinked by radiation or even by chemical means as through use of organic peroxides without loss of the surprisingly increased insulation resistance and insulation resistance stability.

Abstract: ABSTRACT         A de-boning machine comprises a pair of dies which are adapted to close around a meat portion in which a bone is located such that the meat is displaced laterally from the bone in response to closing of the dies while the bone remains in tact.          The dies preferably have opposite disposed de-boning faces in which a bone locating recess is formed.  To reduce the likelihood of damage to the bone resulting from closing of the dies, the bone receiving recess is filled with a resiliently deformable material such as a food grade rubber.  In order to separate the meat which has been laterally displaced from the bone, a cutter is provided laterally outwardly from the bone receiving recess, the cutter being operable upon final closing of the dies.  In order to prevent over-compression of the resilient liner, a yieldable support is provided at at least the critical support areas, the yieldable support being adapted to yield to prevent excessive compressive loads being applied to the bone as a result of compression of the liners.  The mechanism also includes a loading device which permits individual meat pieces to be loaded into the de-boning dies as required in use.  The loading mechanism preferably includes a clamping mechanism which serves to clamp a bone which will be located outwardly from the dies during the boning operation.  The mechanism being arranged to permit movement of the gripper relative to the de-boning dies to rip the bladebone from the meat which surrounds it and to separate the bladebone from the arm bone.
